It depends on which woman I'm looking at. Different women have a different strong body part, or parts.
I tend to gravitate towards the hips. The curvier the better, within reason of course. It's not just the hips, but the contours of the waistline and how it leads into the hips when looking at her from the front or back. That and her curviness in general. Man, that shit gets me soooo
, especially when she knows how to use the curves to turn me into steel.
